It's a partisan assertion of a narrow political group, not generally accepted. That doesn't mean you shouldn't make the assertion, but to say it's somehow a truth generally acknowledged is false.
That's said The arguments against Congressional delegation to the executive existed long before qanon and the arguments of limited congressional power date back to before 1789 so unless q anon existed in 1700's then you're just using a modern fringe group in a very poor attempt to sideline the conversation no different than calling everything that you disagree with racist or sexist or some other ism
For there still this idea that Congress and the executive should work together as a novel one and not one shared by the Constitution separately equal is critical to the functioning of our governance The key word there being separate.
The cozy relationship between the executive and Congress is a problem
Under the current "living document" doctrine adopted by the court the power of the federal government is limitless, and there really is not need for Section 8 of Article 1 as to them "Necessary and Proper Clause" makes everything congress deems " Necessary and Proper Clause" to be constitution, a moronic interpretation of the Constitution who's entire purpose was to limit federal power.
The current court is set to role back some of that, I hope it does but it is unlikely they will go as far I want them to... Which includes going all the way back and reversing Wickard v. Filburn and every decision that built off that wrong.
